HINGE.

PECIFIGATIClN forming part of Letters Patent No. 685, dated October '22,1901- Application filed. may 29, i901. stun rt. 252,404. (No model.)

To aZZ whom it may concern/.-

Be it kiiown that 1, SWEET B.--NILsEN, of rookston, in the county ofPolk and State of Minnesota, have invented certain new and usefulImprovements in Hinges; and I do hereby declare the following to be afull, clear, and eicact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention contemplates certain new and useful improvements inhinges.

The object is to provide improved means for adjusting the connectionbetween the leaves to permit of doors being attached to jambs of varyingthicknesses and also to overcome the unevenness resulting from warping.

The invention will be hereinafter fully set forth, and particularlypointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective. Fig. 2is an end view showing in dotted lines the positions to which the leavesmay be adjusted. Fig. 3 is a cross-' sectional view on line 3 3, Fig. 1.Fig. 4cis a View of one of the leaves. Fig. 5 shows the yoke connectionbetween the leaves. Figs. 6 and 7 are views of the pintles.

Referring to the drawings, 1 and 2 designate the leaves of a hinge. Leaf1 is provided with ears 3, through which and the outer apertures of thehorizontal arms 4 of a yoke 5 is passed a pintle 6, preferably square incross-section at its center 7. A coiled spring 8 on this pintle tends tohold leaf 1 in its normal position. Leaf 2 is also provided with ears 9,through which and the inner apertures of the horizontal arms of the yokeis passed its pintle 10. Between ears 9 is a segmental rack 12, whichextends from a block 13, slid- This rack is engaged by teeth let of thevertical arm of yoke 5. The pintle 10 is cut out at one side of itscentral portion to form a cam-like section 15 of length equal to thewidth of rack 12, the movement of which is controlled by said pintle.When the latter is turned so that its cut-out is adjacent to the rack,the latter may be moved slightly toward the pintle and out of engagementwith teeth 14.; but

when the pintle is given a half-turn itscamlike surface will force therack outward into engagement with the yoke.

The yoke 5 forms the connection between the two leaves. It will be notedthat the pivot on which the hinge moves when the door is opening orclosing is that formed by leaf 1 and the outer apertures of the horizontal arms of the yoke. It will also be noted that the yoke, beingadjustabl'y connected to leaf 2, may be so moved as to throw the nor malposition of leaf 1 forward or rearward of the vertical plane of leaf 2.To effect this adjustment, it is only necessary to loosen the nut on theend of pintle 10 and give the lat ter a half-turn. The yoke may then beadj usted to move leaf 1 to the required position to fit the door or toovercome any unevenness between the casing and the door. The pintle V isthen again turned to bind the segmental rack against the yoke, and thenut on the end of the pintle being tightened the parts are firmly heldin their new position.

I claim as my invention- 1. In a hinge, a connection between the leavesforming the pivotbearing for one leaf and means for adjusting suchconnection relatively to the other leaf for regulating the relativepositions of the two leaves, as set forth.

2. In a hinge, a connection between the leaves forming the pivot-bearingfor one leaf and itself adjustably mounted on the other leaf, andadjustable means for controlling the position of such connection, as setforth.

3. A hinge having two leaves, a yoke adjustably mounted on one of saidleaves and pivotally secured to the other leaf, and means on saidfirst-mentioned leaf for adjusting the position of said yoke, as setforth.

4. A hinge having two leaves, a yoke adj ustably mounted on one. of saidleaves and pivotally secured to the other leaf, and an adj ustablemember on said first-mentioned leaf designed to engage and hold saidyoke in its adjusted position, substantially as set forth. 5. A hingehaving two leaves provided with ears, a yoke movably connected to theears of one of said leaves by a pintle, said pintle having a cam-likecentral portion, and said yoke having a toothed portion and pivotallyconnected to the ears of the other leaf, and a segmental rack on saidfirst-mentioned leaf designed, by means of said pintle, to be held inand released from engagement with the 5 teeth of said yoke,substantially as and for the purpose set forth.

6. A hinge having two leaves, a yoke connecting said leaves, means foradjusting the position of the yoke to change the vertical 1o plane ofits pivotal connection to one leaf relatively to the vertical plane ofthe other leaf, and a spring for acting on said first-mentioned leaf,substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscrib- 15' ing witnesses.
